Application filed April '10, 1912.

To all whom it may concern Be it known that 1, JOHN C. il-lnnens, a citizen of the United States, residing at Des Moines, in the county of Polk and State ct Iowa, have invented a new and useful Loose Sheet Holder, of which the following is a specification.

My invention relates to devices for detachably binding sheets in cover or hinder.

The object of my invention is to provide a loose sheet holder of extremely durable and inexpensive construction, for detachably so curing sheets in a book cover or binding, which device is easily operated for inserting sheets or for removing any or all of the sheets in a book, and which grips and holds the sheets firmly in the holder.

More particularly, it is my object to prothrough the opening 1.6 and then bent and ride a device made of spring metal, having an arm designed to yieldingly engage sheets or leaves of paper, and grip them firmly against a flat surface and also having means for securing said arm in such gripping position, said device being so constructed and arranged that the arm may be quickly and.

easily released for inserting or removing sheets of paper.

A further object is to provide a device of this class, in which the parts are so arranged as to occupy a minimum of space within a book cover.

My invention consists in certain details, in the arrangement, construction, and combination of the various parts of the device. whereby the objects contemplated are at tained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows a perspective view of a book cover, equipped. with my improved loose sheet holder. Fig. 2 shows a detail view partly in section of a part of my improved loose sheet holder. Fig. shows a detail, sectional view of a book cover and part of my loose sheet holder. ll: shows a perspective View of another form ot my loose sheet holder. Fig. 5 shows sectional detail view of a book cover, and the other term of my loose sheet holder.

In the accompanying drawing, used the reference numeral 10, to indicate the back of an ordinary book binding or cover, to which is secured the side 11 extending at right angles to the back 10. The side 12 hinged to the opposite edge of the back 10.

an angle bar having a back 13 and a base 13 of rigid material. In the one form of my device, I secure to the inner side of the back i plates l t, preferably two in niiunber, with. their lower edges resting on tl e base 13, which plates over the greater part of their length, are spaced apart from the bacl; 13 to which they are secured, leaving a pocket 15 between the said back and the plate l-il. in the portion of each plate .l-l spaced. apart from the back 1?) to which said plate is secured, I provide an opening 16 and on the back 13 near each plate 1 1-, ll proride an inwardly extending lug 17, the purpose of which will be hereinafter described. in the pocket 15, I arrange a convolute spring 18, in a plane parallel. and adjacent to the back 13, having one end extended extended toward the base in a plane parallel with the back to which the plate 1+]; is secured. The extreme end, 18, or the portion of the spring just mentioned, is bent at right angles thereto, and is designed to rest adjacent to the surface of the base 13 to yieldingly hold sheets oil paper 530, as shown in lfigs. 1 and The other end of the spring 18 normally extends upwardly from the pocket 15, in a plane parallel to bacl: 13 shown in Fig. l. The spring 18 and the ends thereof, are arranged so that when it is desired to press the end i8 against the flange 13 the end 18" may be pressed downwardly underneath the lug l7 and the resiliency ot' the spring will yieldagainstthe said flange. I preferably provide for each of the flanges 13, two of the springs 18, as shown in Figs. 1 and 4t.

In Figs. and l have shown another form of my improved loos-e sheet holder, COZllPTClSGtl of an angle bar having a base 20 and baclc 21, which latter is provided with o- :enings to receive the ends of co-nvolute springs. Convolute springs preferably two in number, are arranged adjacent to the outer surface of and in a plane parallel to said surface of the back 21, with one end extending through the opening in the back and then extended toward the back 20 in a plane parallel with the plane in which the springs 22 lie. The extreme end 22 of the portion of the spring just mentioned, is bentat right angles to said portion, as shown in 4t, and is designed to rest on the upper surface of the base 20. Lugs 43 are formed on the edge of the flange 21, adjacent to the springs 22. The other ends 22 of the springs 22, normally extend upwardly away from the back 21, in planes parallel to said back 21, as shown by the dotted lines in Fig. at. hen it is desired to hold the ends 22 of the spring 22, in position for holding sheets of paper against the flange 20, the ends 22 of said springs are pressed downwardly beneath the lugs 23, as shown in Fig. 4, and the springs are so arranged that when the ends are in their last named position, the resiliency of the springs holds the ends 22 thereof, firmly against the flange 20. The form of my loose sheet holder shown in Figs. 4 and 5, is designed to be secured in a book cover or binder, having sides 24 and 25 and a back 26, hinged to each side. The base 20 is secured to the side 24, adjacent to the back 26 in the following manner: In the flange 20, are cut slits preferably U shaped, thereby forming tongues 27. The tongues 27 are inserted into the side 2%, as shown by the dotted lines in Fig. 5, in position parallel with the body of the base 20.

The other form of my loose sheet holder, may be secured in the cover or binder in the following manner: The parts 13 and 13 are glued to the side and the back 10, and a cloth 28 is glued or pasted over said parts and over the plates 14, as shown in Figs. 3 and 1, thereby protecting the sheets 30 from contact with the back 13 or the plates 14. The cloth 28 is provided with openings to receive the ends of the springs 18. On the base 13*, I provide upwardly eX- tending lugs 31, designed to be received in holes in the sheets 30, thereby enabling me to more quickly and easily insert the sheets 80 in proper position and to hold them there.

In the practical use of my improved loose sheet holder, assuming that either form is secured to the cover or binder in the manner hereinbefore set forth, I turn back the upper side of the cover and release the ends 18 or 22" as the case may be, from the lugs by which they are held, and raise the ends 18 or 22 The sheets of paper 30 are then inserted beneath the ends 18 or 22, and the ends 18 or 22 are placed under the lugs 17 or 23, thereby causing the ends 18 or 22 to firmly grip said sheets of paper against the adjacent flange of the angle bar. IVhen it is desired to release any or all of the sheets or paper, the ends of the springs are released from the lugs which hold them,

and the sheets of paper may be readily removed.

My improved loose sheet holder is simple and inexpensive to make, and extremely durable. Sheets of paper are firmly gripped and held against the base of the angle bar, and may be easily and quickly inserted or removed. There are no parts which are likely to catch and tear the sheets of paper. An especial advantage is found in the fact that the body of the spring and the ends 18" or 22 as the case may be are located adjacent to and in planes parallel to the back of the holder thus occupying a minimum of space. In the form shown in Figs. 4 and 5, the spring occupies the space always found in a book between the leaves and the back of the cover. The ends 18 and 22 are so located as not in any way to interfere with the cover.

I claim as my invention: I

1. In a device of the class described, an angle bar, having a base and a back, a convolnte spring arranged adjacent to one surface of the said back in a plane parallel thereto, having one end arranged to rest on the upper surface of the base for holding sheets of paper, the other end of said spring extending normally upwardly from said back in a plane parallel thereto, and a lug on said angle bar arranged to engage and hold said last named end of the spring, in such position that the resiliency of the spring will yieldingly hold the first end in its sheet holding position.

2. In a device of the class described, the combination of a book cover, an angle bar secured therein adjacent to the back thereof, having a base and a back, a convolute spring arranged adjacent to the outer surface of said back, extending through and rotatably mounted in said back and then extended toward the upper surface of said base and having an extra end bent at right angles to said inclined portion and designed to hold sheets of paper on said base, the other end of said spring being inclined normally upward away from the body of said spring and means for detachably securing the last named end of said spring in such position that the resiliency of the spring will yieldingly hold the'said extreme end in its sheet holding position.
